以黑龙江省东北林业大学帽儿山实验林场尖砬沟森林培育实验站23a生水曲柳落叶松带状混交林为研究对象,测定对落叶松林带进行不同方式结构调整后水曲柳林带土壤理化性质的变化。结果表明:不同结构调整方式,对水曲柳林带土壤物理性质未产生显著影响,对土壤部分化学性质影响显著。去边行调整后水曲柳林带土壤,上层和中层的水解N含量显著大于其它调整及对照组对应层次的含量(P<0.05),上层的有机质含量也明显大于其它调整及对照组的含量(P<0.05)。对落叶松去边行与隔株去株和品字型均匀伐相比,去边行表现出更好的改土效果。
The Larix kaempferi-Larix gmelini Mixed Forests in Jian’ergou Experimental Station of Mao’ergou Experimental Station of Mao’er Mountain Experimental Forest Farm of Mao Zedong National Forest Farm in Northeast Forestry University of Heilongjiang Province were used to study the physical and chemical characteristics of Larix kaempferi forest with different ways of structural adjustment Changes in nature. The results showed that: different structural adjustment methods had no significant effect on the physical properties of the soil in the Fraxinus mandshurica forest, and had a significant effect on some soil chemical properties. The contents of hydrolyzed N in upper and middle layers were significantly larger than those in other adjustment and control groups (P <0.05). The contents of organic matter in the upper layer were also significantly higher than those in other adjustment and control groups P <0.05). The larch to go to the line and the strain to strains and the average font type compared to go to the line shows better soil improvement effect.
